It's a white Christmas in the United States today, with snow falling from Seattle to Maine.

    Northeast

    Biting winds with snow swept the Northeast.

    Earlier, up to 15 inches of snow fell during a snow storm in Maine, while up to one foot fell in New Hampshire. Winds reached 76 mph on Cape Cod, Massachusetts, while up to 61 mph winds tore through Long Island, New York. Falling snow collected on the runways at Boston's Logan International Airport, causing temporary flight delays.

    The wind was so severe in Pennsylvania and New Jersey that the annual (重演) of George Washington and his soldiers'crossing the Delaware River was canceled, the Washington Crossing Historic Park told ABC News.

    Midwest

    Heavy lake effect snow fell in western Michigan.

    The National Weather Service has issued a wind-chill warning and advisory (公告) from Montana to Michigan. Bitter cold air in the Midwest produced wind chills Monday morning as low as minus 48 degrees in North Dakota and minus 47 in northern Minnesota.

    As this bitter cold made its way east overnight, it was expected to move over relatively mild Great Lakes, producing intense lake-effect snow bands capabie of producing 2 to 4 inches of snow in an hour.

    West Coast

    That storm system moved overnight through the Rockies, bringing more snow and the threat of avalanches(雪崩). The National Weather Service has issued an avalanche warning for the Wasatch Range Mountains outside Salt Lake City.

    French writer Frantz Fanon once said: "To speak a language is to take on a world, a culture." Since the world changes every day, so does our language.

    More than 300 new words and phrases have recently made it into the Oxford Dictionary Online, and in one way or another they are all reflections of today's changing world.

    After a year that was politically unstable, it's not hard to understand the fact that people's political views are one of the main drives of our expanding vocabulary. One example is "clicktivism", a compound of "click" and "activism". It refers to "armchair activists" -- people who support a political or social cause, but only show their support from behind a computer or smart phone.

    "We had all the words around Brexit (脱欧) in the last update and we are now starting to see all the words around Trump coming into the dictionary," Angus Stevenson, Oxford Dictionaries' head of content development, told The Guardian.

    Lifestyle is also changing our language. For example, "fitspiration -- a compound of fit and inspiration -- refers to a person or thing that encourages one to exercise and stay fit and healthy. The phrase "climate refugee" -- someone who is forced to leave their home due to climate change -- reflects people's concern for the environment.

    According to Stevenson, social media was the main source for the new expressions "People feel much freer to coin their own words these days." he said.

    But still, not all newly- invented words get the chance to make their way into a mainstream dictionary. If you want to create your own hit words, Angus Stevenson suggests that you should not only make sure that they are expressive and meaningful, but also have an attractive sound so that people will enjoy saying them out loud.

    As children we are well-trained to find the right answer. We are rewarded for A's, the honor roll and acing the test. Our education trains us to follow the rules and deliver the expected answers. When we do, awards and congratulations follow. Yet when we grow up, it gets a little harder. Life and careers don't have tests with an A if we get the "right" answer.

    I recently had coffee with a college student who will graduate. She is struggling with what she wants for her career. She wants her parents to be proud of her and to continue the success she has had in school. She also talked about other students in her graduating class who are set to do "some big things," like working for impressive companies. Yet she wasn't sure of the right answer for using her degree. She said that deep down she was hoping that someone might give her the answer.

    We both agreed that it comes down to not looking for the right answer, but her answer. The grown-up definition of the "right answer" is different than that in school. What would you do if you weren't afraid? It takes time to know these answers. And they can change over time and at any point in your career. My encouragement is to get valued advice and input, of course, but finally to look within yourself for the answers. It helps to come back to:

What do I want to be known for? What is my definition of success? What am I best at?

    If I had no fears, what would I do?

    What is one step I can take today to move me toward my goal (even if it's not perfectly clear)?

    I find these types of questions are more helpful at getting to our unique answer rather than "right answer" questions, such as: What will my parents want? What degree or job will mark me as accomplished to the world? What is my best option based on where I work today?

    A walk through the galleries of Quebec's Montreal Museum of Fine Arts (MMFA) places individuals face-to-face with some 43,000 artworks ranging from Chinese ceramics(陶瓷制品) to Inuit sculpture.

    While the visiting is an incredible cultural experience, a group of local physicians will soon be able to prescribe(开处方) museum visits as treatment for some illnesses.

"We know that art contributes to neural(神经的) activity," said MMFA director Nathalie Bondil. "What we see is that being in contact with art can really help your well-being."

Hélène Boyer, vice president of a Montreal-based medical association, explains that museum visits have been shown to increase levels of serotonin, a neurotransmitter(神经传导物质) known as the "happy chemical" which helps to lift mood.

    According to Boyer, the small increase in hormones(荷尔蒙)associated with enjoying an afternoon of art is similar to that offered by exercise, making museum prescriptions ideal for the elderly experiencing pain that prevents them from regularly joining in physical activity.

    The museum visits are designed to improve traditional methods. As Bondil notes, spending time in a peaceful environment can provide a welcome distraction. "What is most important is this experience can help them escape from their own pain," she says. "When you enter the museum, you escape from the speed of our daily life."

    "I am convinced that in the 21st century, culture will be what physical activity was for health in the 20th century," said Bondil. "Some people would do well to recall that just in the 19^th century, sports were believed to do harm to the body. Just as doctors now prescribe exercise, they will be able to prescribe a visit to the MMFA."

    Who decided that blue jeans and T-shirts are "cool" for kids to wear today? Who designs the clothes you see for sale in stores? All of these questions concern the world of fashion.

    Fashion refers to the styles of dress that are currently popular. Fashion goes beyond just clothes, though. It's important for some people to wear only the latest fashions and styles. For others, though, keeping up with trends isn't that important. The one thing that stays the same with fashion is this: it always changes!

    In the 1960s and 1970s, hippies made bell-bottomed blue jeans popular. In the 1980s, Michael Jackson made parachute pants (降落伞裤) all the fashion. Now try to find these items in today's clothing stores!

Why do fashions change? The answer is probably as simple as the fact that people change. Over time, the new replaces the old. People are influenced greatly by popular culture, including athletes, musicians, movie stars, as well as popular films, television shows, books and music. We are also influenced by the fashion industry's advertising.

    The stars of popular culture are always searching for a new angle to maintain (保持) their popularity. Often these new angles come in the form of new clothing or hairstyles. When people see these new styles, they often want to imitate their favorite stars. To do so, they seek out the latest fashions to make themselves look like the people they want to imitate. In this way, fashions evolve and change over time.

    For years, clothes have been used to separate people into groups. Even today, brand-name clothing that is more expensive than other types of clothing can be used by some people to distinguish themselves from others.

    Unfortunately, this can often have the effect of distancing certain groups from others. Don't forget that it's always OK to develop your own sense of style that is unique and separate from what the fashion world determines! Stay true to yourself and let your personality — not your clothes — speak for who you are!

    People speak English in different parts of the world. The same words can be used in different ways, depending on where you live. People can also have completely different ways of saying the same thing.

    The Oxford English Dictionary (OED) is asking the public to help it add new words. Editors want to find the regional differences in English around the world. They want to expand its record of the language.

    Last year, the OED, BBC Radio and the Forward Arts Foundation teamed up to find local words in the United Kingdom. It resulted in more than 100 regional words and phrases being added to the dictionary. One was "cuddy wifter", which means a left-handed person.

    Now, the OED is widening its search to English speakers around the world. Eleanor Maier, an editor at OED, said the response has been great. Editors are listing a bunch of suggestions to include in the dictionary.

    These include Hawaii's "hammajang", which means "in a disorderly state". Another is the word for a swimming costume, "dookers" or "duckers". It is used in Scotland.

    The OED also might include the word "frog-drowner", which Americans might use to describe a downpour of rain. Another possibility is "brick". It means "very cold" to people in New Jersey and New York City.

    The dictionary has already found that, depending on location, a picture hanging off center might be described as "agley". It might also be called "catawampous" or "ahoo".

    "The OED aims to cover all types of English," Maier said. That includes scientific words, slang and regional language. Maier also said that it can be difficult for the OED's editors to identify regional words. The terms are more often spoken than written down.

    The appeal is called Words Where You Are. It is looking for more suggestions. "We were surprised and pleased by the number of regional words we were able to include," said Maier.
